Resources for RAA228227
Description
The RAA228227 is a digital dual output multiphase (X+Y ≤ 16) PWM controller with an Adaptive Voltage Scaling Bus (AVSBus) interface.
The RAA228227 controller can be configured to support any required phase assignment up to a maximum of 16 phases across the two outputs (X+Y). For example, 15+1, 14+2, 13+3, 8+8, or even single output operation as a 16+0 configuration are supported. Increased power density, combined with support for the PMBus V1.3 and Adaptive Voltage Scaling Bus (AVSBus) interfaces, allows the RAA228227 to support any demanding power supply requirement.
The RAA228227 AVSBus interface complements PMBus by providing a common high-speed interface that accelerates point-to-point communication. The communication occurs between the controller and the load to statically and dynamically control the processor voltage, which delivers a balanced power-efficient design.
The RAA228227 uses the proprietary Renesas digital synthetic current modulation scheme to achieve the industry-best combination of transient response, ease of tuning, and efficiency across the full load range. The diode emulation and automatic phase add/drop features allow you to extract maximum efficiency from the converter regardless of load conditions. You can use the intuitive Renesas PowerNavigator™ software to configure and monitor the RAA228227.
With minimal external components, easy configuration, robust fault management, and highly accurate regulation capability, implementing a high-performance multiphase regulator has never been easier.
